Deleted ESP (EFI) partition - unable to create new one

[gabriel78]

I have an Asus Ultrabook UX32A.
I have a small SDD with 24 GB and a big HDD with 500 GB.
Windows 8 was pre-installed.
I deleted ALL Partitions on both discs (because I though I do not need any of them anymore) and installed Ubuntu 16.04.
I created a small partition at the beginning of the SSD and marked it in the installation process as efi.
On the remaining partition of the SSD, I installed Ubuntu 16.04.
After the installation, I was unable to boot into the new installed Ubuntu 16.04.
I tried boot-repair, but without any luck.

Here is a Boot-Summary of boot-repair (I installed it in the live system. The drive of the livesystem is /dev/sdc/)

Please any help!

But you apparently installed in legacy mode, without a grub-bios partition on a GPT disk, so no boot. Reinstall in UEFI mode.

In UEFI mode grub only installs to the ESP on sda. So have an ESP on your hard drive.
But use gpt partitioning on both drives and put just / (root) on SSD. Then use HDD for either /home or large data partition like /mnt/data and link all typical /home folders into /home on SSD.

After you create the ESP on sda, then grub will install correctly in UEFI mode.
But you need to boot Boot-Repair in UEFI mode.
